Module 5WK50720HBR – Continental CAS4 for BMW 5 Series F10 F11
Original Continental CAS4 CA access and start control module fitted to selected BMW 5 Series F10 and F11 vehicles. The unit communicates with the immobiliser, keys and other control modules responsible for authorising vehicle start-up.
Applications of the 5WK50720HBR CAS4 module
- BMW 5 Series F10 – saloon;
- BMW 5 Series F11 – Touring estate;
- selected vehicles manufactured approximately between 2012 and 2013;
- vehicles equipped with the CAS4 CA system.
The CAS4 module was produced in several hardware and software variants, regardless of engine capacity. Before ordering, compare 5WK50720HBR and BMW part numbers 61359301518, 9301518 and 61.35-9 301 518.9-01 with the label on the original unit. Final compatibility should be confirmed using the vehicle’s VIN.
Common symptoms of a faulty CAS4 module
- no response when the Start/Stop button is pressed;
- the key is not recognised or an incorrect-key warning appears;
- the starter motor does not operate despite a charged battery;
- problems locking or unlocking the steering column;
- no diagnostic communication with the CAS module;
- intermittent central locking or Comfort Access faults.
Similar symptoms can also be caused by a discharged key, weak vehicle battery, damaged wiring, faulty access-system antenna or lost synchronisation with other modules. A complete vehicle diagnosis should be performed before replacing the CAS4.
CAS4 programming and preparation
The module is supplied as a tested set with keys. It is not a universal Plug & Play part and must be correctly matched to the vehicle’s immobiliser system and associated control units before the engine can be started.
- data can be transferred from the original CAS4 if its memory can be read correctly;
- cloning transfers identification data, registered keys and information required for start authorisation;
- when using the supplied set data, the ISN may need to be matched to the DME or DDE engine control unit;
- the module may require coding according to the vehicle’s equipment specification;
- the procedure should be carried out by a workshop equipped to program BMW CAS4 systems.
Before selecting a preparation method, it is necessary to establish whether the original CAS4 still communicates and whether a complete memory read is possible.
